Respiratory Therapy Equipment Guidelines


Introduction

Published reports have documented the role of respiratory equipment as an important source of cross infection with microorganisms causing respiratory diseases. Nebulizers have been shown to be capable of generating aerosols containing large numbers of visible bacteria. Nebulizers generate particles of a size which can penetrate to the lower respiratory tract; therefore contaminated nebulizers are more dangerous potential disseminators of pulmonary infection than are humidifiers or heat and moisture exchange devices. The initial source of bacterial contamination may be solutions or medications contaminated before nebulization.

Procedures

Reduce Contamination of Equipment
Make every effort to eliminate the sources of contamination in equipment, accessories and solutions. Some policy measures include: the use of sterile medications, single-dose vials, discarding unused portions of sterile or deionized water daily, rinsing and drying medication nebulizers after each use, replacing heat-moisture exchangers every 24 hours, replacing in-use nebulizers, IPPB tubing and filters every 48 hours, replacing oxygen hoods and in-line suction catheters every 7 days or when gross soiling is apparent, and replaing ventilator circuits every 14 days or when gross soiling is apparent.

Clean Respiratory Therapy Equipment
Instruct personnel responsible for cleaning the equipment in proper handling necessary to reduce the risk of infection and to reduce contamination of the cleaning area. Follow manufacturers recommendations, and thoroughly wash and rinse equipment prior to sterilization. Clean and disinfect the exterior surfaces of large pieces of equipment (ventilators, IPPB machines, end tidal CO2 monitors) between patients. Cover all equipment when not in use.
